                                            热水锅炉的工作原理
                                            来源: 中国锅炉网 时间:2017年03月08日 字体:[ ]
                                              山东热水锅炉主要由锅壳封头、炉胆、炉胆顶、下封圈、冲天管及横水管组成,近几年得到了迅速的发展与推广。现在我们大体了解一下热水锅炉的工作原理。
                                              热水锅炉是提供热水的热能转换设备,它把燃烧燃料?#22836;?#20986;的热量传递给锅内的水,使锅内水温度升高供用户取暖或生活用。然后用一次循环水泵循环抽出锅炉内的热水,送至板式换热器热介质进口,放热后经板式换热器热介质出口回到锅炉再加热,形成一次系统的循环,当锅炉内的一次循环水损失减少时,由膨胀水箱及时补充;同时二次循环水泵循环抽回热用户的回水,送至板式换热器的二次进口,吸热后由板式换热器的二次出口送往热用户,形成二次系统的循环,当二次循环系统的水损失减少时,由补水水箱内的水经过补水泵及时补充;燃料燃烧的产物经过尾部受热面后通过烟囱引至室外。
                                              热水锅炉进口和出口流动的都是水,大多数是通过水泵的压力进行强制循环,也有些在锅炉本体内靠水温不同所造成的重度差进行自然循环。
